A new type of subway section excavation method and device

Abstract

The invention discloses a novel subway section excavating method and device. The novel subway section excavating device comprises a movable base. A traction guiding seat is mounted at one end of the movable base. A grooving mechanism is mounted at the other end of the movable base and comprises a working table connected to the surface of the movable base. A grooving seat is mounted on the workingtable. The surface of the grooving seat is connected with an electric pushing rod. The tail end of the electric pushing rod is connected with a power seat. The two sides of the surface of the power seat are connected with driving columns. The tail ends of the driving columns are connected with grooving assemblies. The side, close to the exterior, of the power seat is connected with a graded bulldozing mechanism. The power seat is internally provided with an airflow soil-loosening mechanism and a soil probing mechanism. Conveying mechanisms used for soil conveying after grooving are mounted onthe two sides of the surface of the movable base correspondingly. Soil is excavated through the composite actions of the grooving mechanism and the graded bulldozing mechanism, the size of the excavated soil is small, the excavated soil is not prone to being accumulated and convenient to convey, the overall cooling effect is good, and cleaning is convenient.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a novel subway section excavation method and device. Background technique [0002] Subway is a form of railway transportation, which refers to the urban rail transit system that mainly operates underground, that is, the abbreviation of "underground railway" or "underground railway". Many such systems are designed to match the built environment and consider construction and operating costs It may be turned into a ground or elevated road section outside the city center. The subway is a proprietary, high-density, high-capacity urban rail transit system covering various underground and above-ground road rights in urban areas. The Taiwan Metro is called "MRT ". [0003] In addition to subways, elevated railways or railways laid on the road are also included. Therefore, the subway has exclusive rights of way and no level crossing, which is also a fundamental sign that the s...

AI Technical Summary

Problems solved by technology

[0008] (1) When the general excavation device excavates the soil, it cannot detect the soil condition of the excavation in real time, which is not conducive to the safety of the excavation process;

[0009] (2) Moreover, excavation is carried out by a single device, which not only has low excavation efficiency, but also easily damages the excavation device, which affects the excavation work;

[0010] (3) When excavating soil, the general device needs to use external devices to transport the soil out, which is inconvenient to operate in a small space, and sometimes the individual volume of excavated soil is large, which is not convenient for transportation
